GRAIN-HEADER.

Specification of Letters Patent.

Application filed October 7, 1909. Serial No. 521,611.

To all whom it may concern:

Be it known that I, Rain) (1' Townes, a citizen of the United States, residing at Fairport, in the county: of Russell and State of Kansas, have inverted certain new and useful Improvements in Grain-Headers, of which the following is a specification.

This invention relates to grain headers and more especially to machines of the character mentioned driven by an engine or other motor mounted upon the machine, and my object is to produce an eflicient and reliable machine in which the cutting mechanism may be adjusted vertically or pivotally toward and from the ground.

A further object is to produce a machine and comparatively inexpensive construction.

With these objects in'view and others as hereinafter appear, the invention consists in certain novel and e'culiar features of construction and organization as hereinafter described and claimed; and 1n order that 1t upon a pair of rear carrying wheels 2, and

a pair of front carrying-wheels 3, the latter bein journaled 1n yokes 4 swiveled in the side are of the frame and provided at the u per sides of the latter with rigid rear wardly-projecting crank arms 5 pivotally connected by a cross bar 6.

7 is a link pivotally connecting one end of cross bar 6 with the crank arm 8 of a worm segment 9 pivoted at 10 on a cross bar 11 and engaged by a worm-shaft 12 journaled in any suitable manner not shown, and disposed at. angle of substantially forty-five de rees an provided at its upper or rear en with a hand-wheel or steering-wheel 13.

14 is a -casing containing an engine not shown mounted on-the rear end of the mal 20 connected" by a chain 21 to a large sprocket wheel 22 bearmga ri id relation to the rear wheels 2, so that in the operation of the engine in one direction or the other, the wheels 2 shall be driven forwardly or rearwardly and ropel the machine accordingly. Secured to the front corners of the frame are bifurcated or forked brackets 23 and journaled therein are cog wheels 24, and pivoted on the shaft 25 of-the cog wheels are sleeves 26 in which fit slidingly rack bars 27 meshing with said cog wheels. 'Secured to and midway the length of the front end-bar of frame 1 is a forked bearing bracket 28 and arranged within said bracket and secured upon shaft 25 is a worm wheel 29, engaged by a suitably journaled worm shaft 30 provided with a hand-wheel 31, so that through said hand-wheel vertical movement, upward or downward, may be transmitted to the rack bars 27. Pivotally connected to the upper ends of the rack bars at 32 is a V-shapcd link 33, the rear end of the same being pivoted to a sleeve 34 fitting on an upright 35 pivotally mounted on across bar 36, and pivoted to said sleeve and extending downward and rearward therefrom through a suitable guide or cross bar 37 is a rod 38 provided at its rear end with a nut 39, a

spring 40 being interposed between the nut and rod and tending to swing upright 35 rearward. Pivoted at 41 to a bracket 42 carried by a cross bar 43 'of the frame is a swing bar 44 provided with a longitudinal series of holes 45 and fitting adjustably on saidswing bar is a sleeve 46 secured at the desired point of adjustment on the bar 44 by a removable pin 47 extending through the sleeve 46 and one of the series of perforations of bar 44.

48 is an extensible and contractible rod and pivotally connected at its rear end to sleeve 46 and at its front end to the upper end of the upright 35, this rod being adapted to sustain tensile strain, and pivotally connected to said sleeve 46 and to upright 35 coincidentally with the pivotal point of the latter is a brace 49, said brace and rod 48 bearing a rearward converging relation.

Whenit is desired to tilt the rack bars in one direction or the other the person in control of the machine withdraws pin 47 and slides sleeve 46 upward or downward upon swing bar 44. When the sleeve 46 is slid upward the rack bars through the weight of the parts carried thereby, swing around shaft 25 as the pivot. As this action Patented May 31, 194(1).-

occurs the pivoted upright is swung forward by the V-shaped link 33, and the sleeve-carrying bar 44: is' swung in the same direction through its connection with upright by means of rod 48, it being noted in this connection that the movements described of the rack bar, upright 35 and swing bar as are cushioned byspring 4:0,

downward movement of said sleeve revers--' ing the adjustment of the parts referred to, the spring 40 cooperating in such reverse adjustment of said parts.

The rack bars are provided at their lower ends with forwardly-projecting arms connected by parallel transverse bars 51 and constituting a frame in conjunction therewith, for the support of the customary traveling con'veyer 52 adapted to receive the heads of the grain'severed by the usual cutting mechanism 53. Erected upon the last-named frame is a framework 5 1 of any suitable or preferred type and journaled in said framework above the cutting mech-- anism is a reel 55 adapted to knock the grain as it is severed by the cutting mechanism,

' shaft 57; is'equipped with a sprocketwheel 61 connected by a chain 62 to a sprocket wheel 68 rotatable with the reel. The drive shafts 64 and 65 of the elevator conveyer are driven by tumbling shafts 66 and 67 universally coupled to longitudinal shafts 68 and 69 respectively, shaft 69 being connected by a bevel gear 70 with a bevel gear 71 on shaft 57. Said shaft is provided with a gear wheel 72 meshing with a gear wheel 73 on shaft 68 to drive the latter. The shaft 64 is equipped at its front end with a wheel 74 provided with a wrist pin 7 5 connected by a link 76 with the reciprocatory cutter bar 77 of the cutting mechanism.

From the above it will be seen that the engine is utilized to not only propel the machine in the desired direction but also to drive the operative parts of the machine and that the adjustment of the-sleeve 4:6 is for the purpose ofadjusting the cutting mechanism to operate at different distances from the ground, the tilting of the rack bars dis osing' the cutting mechanism for most e ective o eration upon inclined or rolling ground. l or instance when the machine passes over the,crest of a hill and starts down an incline it is necessary te carried tilt the conveyer-belt-carrying frame down ward so that the cutting mechanism shall be disposed atabout the same distance from the ground that it was when traveling over level ground. In traveling up a hill the tilting adjustment of said frame must be reversed so as to raise the cutting mechanism for the same reason, it being understood of course that the reel and other parts movable with the last-named frame will move with and in the same direction as thecutting mechanism. The s ring a0 is mainly for the purpose of absorb ng the shocks or jars incident to the adjustment of the rackbar-carrying frame.

From the above description it will be apparent that I have produced a grain header embodying the features of advantage enumerated in the statement of the ob ect of the invention and while I have illustrated 'and described the preferred embodiment of the same it will be apparent that it is susceptible of modification in various part1culars without departing from the spirit and scope of the appended claims.
